For this to work, the rump kernel must include the vfs faction,

+.It Fl r Ar total_ram
+Sets the limit of kernel memory allocatable by the server to
+.Ar total_ram
+as opposed to the default which allows the server to allocate as much
+memory as the host will give it.
+This parameter is especially useful for VFS servers, since by
+default the virtual file system will attempt to consume as much
+memory as it can, and accessing large files can cause an excessive
+amount of memory to be used as file system cache.
